Are on the street, if you look (5)
I believe the answer is:
stare
'you look' is the definition.
'stare' can be an answer for 'look' (stare is a kind of look). I'm not sure about the 'you' bit.
'are on the street' is the wordplay.
'on' says to put letters next to each other.
'the street' becomes 'st' (abbreviation).
'are' after 'st' is 'STARE'.
'if' is the link.
Can you help me to learn more?
(Other definitions for stare that I've seen before include "Long fixed look" , "Gaze fixedly" , "Look hard" , "bird" , "Look with fixed gaze" .)
